HORSESHOE.

Specification of Letters Patent.

Patented Sept. 25, 1906.

Application filed May 16,1905- Serial No. 260,699.

To all whom it may concern.-

Be it known that I, CHARLES D. MURPHY, a citizen of the United States,residing at Kingston, in the county of Meeker and State of Minnesota,have invented certain new and useful Improvements in Horseshoes, ofwhich the following is a specification.

My invention relates to soft-tread horseshoes, and more particularly tothose having the heel-calks actuated by a spring or similar device tocushion the same, and thus take up shock and the like.

A further object is to so construct the device that it can be easily andcheaply manufactured and the parts thereof removed and replaced whenwear and repair require the same.

In the drawings forming a part of this specification, and in which likesymbols of reference represent corresponding parts in the several views,the device; Fig. 2, a bottom plan of the same. Fig. 3 is a rear view.Fig. 4: is a perspective view of the heel portion of the shoe upon whichthe spring operates, and Fig. 5 is a perspective view of the springportion detached.

1 designates the horseshoe; 2, the toe-calk of same; 3, thespring-plates 4, the heel portions of shoe; 5, screws, rivets, or thelike connecting the springs 3 to the shoe; and 6, support and guide forheel-calks.

7 and 8 are lugs on shoe adapted to receive and limit arm 9; 10 and 11,recesses in shoe to receive the rear end of spring-carried piece 13togive additional strength {and resiliency to same; 5, screws connectingpiece 13 to 3, and 12 represents screws or the like securing piece 9 toportion 13.

14 represents rear of section 13, adapted to be received in recesses 10and 11, so as to give support and strength, as described, and 15 amodification of spring, which may be substituted for or used inconjunction with the spring shown.

The operation of my device will be apparent from the foregoing. The rearend of piece 13 is first placed in grooves or recesses 10 and 11 andconnected to spring 13 by means of screws or the like, and said springFigure 1 is a side view of is in turn connected to the shoe by screws.The arm 9 is then placed'in position so as to play between the lugs 7and 8, and the device is ready for use. The arm 9 is made detachable, sothat it may be renewed, if needed, same as other portions. The arm 9,portion 13 and piece 3 may, if desired, be made in one piece andconnected by rivets to shoe in place of screws, as the heads of screwssometimes become weak under hard work.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is

1. In a horseshoe, a resiliently-supported tread for the same, a post onthe shoe having a reduced portion so as to form stops at its top andbottom, and an arm on the tread, said arm carrying a lug which isadapted to play between the stops on the post.

2. In a horseshoe, a tread therefor, a recess in the shoe to receive thefront of the tread, a post or lug on the rear of the shoe having acut-away portion so as to form stops at its top and bottom, and an armon the tread adapted to be guided and controlled by the stops on thepost.

3. In a soft-tread horseshoe, a cut-away portion on the shoe, a treadhaving its front portion supported over the same, a post on the cut-awayportion having lugs at its top and bottom, and an arm on the treadadapted to ride between the lugs on the post to guide the tread.

4. In a horseshoe, reduced portions on the heels of the same, recessesformed in the heels of the shoe and leading into the reduced portions,treads yieldingly supported above and having their front portionsresting in the recesses, lugs on the reduced portions having stops attop and bottom, arms connected with the treads and playing between thestops, and a cut-away portion in the treads within which the lugs play.

In testimony whereof I afliX my signature in presence of two witnesses.

CHARLES D. MURPHY.
